2023–24 Serie D

The 2023–24 Serie D is the seventy-fourth season of the top-level Italian non-professional football championship. It represents the fourth tier in the Italian football league system.

Rules
The season will provide a total of nine promotions to Serie C (those being the winners of all nine groups). Teams placed between second and fifth for each group will play a so-called "playoff tournament," starting with two one-legged games played at the best-placed team's home venue:


 * 2nd-placed team vs 5th-placed team;
 * 3rd-placed team vs 4th-placed team.

In case of a draw by the end of the game, two extra times will be played; in case of no winner after that, the best-placed team will advance to the final.

The two winning teams will then play a one-legged final, to be hosted at the best-placed team's home venue, with the same rules as in the first round. The nine playoff winners for each group will be prioritized to fill any potential Serie C league vacancies.

The two bottom-placed teams for each league group are automatically relegated to Eccellenza. Two two-legged relegation playoff games (known in Italian as "play-out") will therefore be played between:


 * 13th-placed team vs 16th-placed team (for 18-team groups), or 15th-placed team vs 18th-placed team (for 20-team groups);
 * 14th-placed team vs 15th-placed team (for 18-team groups), or 16th-placed team vs 17th-placed team (for 20-team groups).

Two extra times will be played in case of an aggregate draw after the second leg; in case of a further aggregate draw, the worst-placed team will be relegated.

In case the two teams have a league gap of at least eight points, the relegation playoff will not take place and the worst-placed team will be automatically relegated instead.

Teams
The league's composition involves nine divisions, grouped geographically and named alphabetically.

Readmissions
On 12 September 2023, the league committee announced that it had admitted La Fenice Amaranto as the phoenix club of Reggina after the latter's exclusion from Serie B, according to the Article 52 of N.O.I.F. regulations. The club was later renamed LFA Reggio Calabria.

Exclusions and withdrawals
On 14 July 2023, the Serie D football committee announced Viterbese and Arzachena had not submitted their league applications. In contrast, Torviscosa had renounced their right to participate in the season.

Successively, the league committee excluded Seregno and Sambenedettese due to financial issues; fellow Serie D club Porto d'Ascoli, renamed San Benedetto Calcio, successively acquired the naming rights of the latter under formal approval by the Italian Football Federation.

On 2 November 2023, after the tenth matchday of the season, Lamezia Terme (Group I) announced they were voluntarily withdrawing from the league; all their games played before their announcement were consequently declared null and void.

On 16 April 2024, Pistoiese were excluded after missing two consecutive league games due to financial issues.

Relegation play-outs
The relegation playout games took place on 12 May 2024 and were hosted by the best-placed team in the regular season. In case of a tie after extra time, the best-placed team would escape relegation.
